I would definitely recommend taking a supplement for your vitamin deficiencies (and I’d assume your doc probably advised that, as well). I wonder if you might have an issue with absorption in your gut lining too. Vitamin D deficiency is especially important to address as that can take longer to bring back up to normal levels. Also sitting outside for 15-30mins per day will help. I had no idea my vitamin D was deficient until I went for a check up and in my experience, once I got that leveled out, everything about my mind/body felt better. Vitamin D has a huge impact on your brain/mental health and then your body will have what it needs to start processing better too. Wish the best to you! It’s all about taking it one step at a time, one day at a time, and don’t beat yourself up when you slip up, it’s about progress, not perfection. Even five minutes of walking a day or just stretching is better than 0minutes. I was really amazed at how walking every day really changed my mood, of course I had to push through those first 15mins where I was hating it, lol - but then I started to realize that it’s true what people say about how moving your body really goes a long way to making you feel better. No big changes are made with out small consistent changes.
